A is for Adventurousness, B is for....

Costco's buyers are remarkably attuned to consumer trends. Solar energy devices, organic produce, and luxury items (e.g, jewelry, bordeaux) at heavily discounted prices are but a few examples of goods that were stocked before customer demand became certain.

Sometimes the buyers make puzzling decisions, however. Last year's chicken coops can no longer be found on warehouse floors, and I'll bet this month's beehives suffer a similar fate. (I wont be a buyer, because of my trouble with bees last year.)

Nevertheless give them an A for adventurousness.
